MACHINE FOR PRINTING GLASSWARE.

SPECIFICATION forming part of Letters Patent No. 491,025, dated January31, 1893.

Application filed May 23, 1891. Serial No. 393,865. (No model.) I

To all whom it may concern:

Be it known that I, CHRISTIAN Z. F. Ror'r, a resident of Pittsburg, inthe county of Allegheny and State of Pennsylvania, have invented anewand useful Improvement in Ma chines for Printing on Glassware; and I dohereby declare the following to bea full, clear, and exact descriptionthereof.

My invention relates to apparatus for decorating lamp chimneys and likearticlesof glass-ware, its object being to provide a form of apparatusby which designs or ornamentations may be imparted to the surface ofsuch articles of glass-ware in rapid succession, to be subsequentlybaked into the glass to retain indelibly the design imparted thereto.

To these ends myinvention comprises, generally stated, a travelingcarriage having a type carrier secured thereto, type so mounted in thetype carrier as to lay with an even horizontal surface for inking, andconform to the bulbous, or other shaped body of the chimney or otherarticle during printing, and mechanism for rotating the chimney at suchspeed that its surface will move with the type block, so that the designmay be printedaround the cylindrical body.

My invention further comprises certain improvements in the arrangementand construction of the several parts embodied in the operation of sucha form of apparatus as above generally stated, all of which will be morefully hereinafter set forth and claimed.

To enable others skilledinthe art to make and use my invention, I willdescribe the same more fully, referring to the accompanying drawings, inwhich Figure 1 is a plan View of the apparatus; Fig. 2a side view; Fig.3 is aplan view showing the carriage advanced to its extreme forwardposition and about toretreat; Fig. 4 is an enlarged side view partlybroken away, with the carriage in its advanced position; Fig. 5isacross-section on line (5 ,5); Fig. 1; Fig. 6 is across-section line(66) Fig. 1, showing the chimney in full lines during the printingoperation; Fig. 7 is an enlarged view of device: for conforming the typeblocks to shape .of; chimney; Fig. 8 is a face view showing the.

chimney holders removed; Fig. 9 represents opposite side to that shownin Fig.4; Fig. ll

is an enlarged longitudinal section of the longitudinal beams formingthe frame and showing the beveled edges of the guide-bars by which thetype blocks are canted; Fig. 12 is an enlarged top view, partly brokenaway, of the frame and the type carrier. Fig. 13 is an enlarged planview of the forward end of my improved printing machine after thetypecarrier has advanced to the front end of the frame and is about torecede;Fig. 14 is across section on the line 14-14, Fig. 13, looking inthe direction of the arrow; Fig. 15 is a cross section on the line151'5, Fig. 13, showing the manner in which the type blocks arejournaledin the type-carrier at the forward end thereof; Fig. 16 is an enlargedView of the sprocket wheel and chain in cross section, together with thecrank arm for reversing the direction of the movement of the carriage.

Like letters indicate like parts.

The frame which supports the apparatus consists of the standards A, thelongitudinal beams A and the cross-beamsA The sliding carriage a-travelsto and fro in the guideways a formed in the longitudinal beams A, and toprovide for this advancement and withdrawal of said carriage a in itsguides, a crank arm b is journaled at oneend on the bearing b secured tothe carriage, the other end of said crank arm being secured to thedriving chain c by bolts or other suitable fastening devices. Thedriving chain c engages with the sprocket wheels 0 0 which are on thesame horizontal plane as the bearing 1), the front wheel 0 being securedto the journald at the forward end of the frame, and the rear sprocketwheel 0 secured to the power shaft 01'. By such a construction thecarriage is drawn forward by the chain and when the crank arm 19 reachesthe sprocket wheel 0 or c it swings on its bearing passing around thewheel, and passing above or below the wheel, and then draws the carriagein the op- .posite direction, the table remaining stationary at one orthe other end of its stroke, when wheel.

Mounted on the carriage a and adapted to travel back and forth therewithis the typecarrier e. The type-carrier e is constructed in accordancewith the design or ornamentation it carries, and the size and shape ofthe article upon which it operates to produce the design. In thedrawings, 1 have illustrated a type-carrier carrying a design for theornamentation of lamp chimneys or such like bulbous bodies, the designitself consisting of three bands encircling the chimney, as shown inFig. 9. The type-carrier e is composed of the side bars e and the endbars 6 It is obvious that to impart the design to the bulbous or convexportion of the lamp chimney, the types embodying the design must conformwith the contour of that portion of the chimney to be ornamented. If,however, the type blocks be permanently secured within the type-carrierwith their faces in conformity with the surface of the chimney to beornamented, it will be a matter of much inconvenience to apply thesubstance to the type blocks which imparts the design to the glass. Toprovide for this inconvenience, the type blocks are so adjusted withinthe type carrier that when in position for applying the substance tothem to impart the design, the faces of said typeblocks present an evenface, but when brought into contact with the chimney they are made toconform thereto in the manner hereinafter set forth.

For this purpose the outer type-blocks f are provided with journals f atthe ends thereof bearing in the bearings f in the end bars e of thetype-carrier. At the forward ends of the type-blocks fare the pins 9held normally horizontal by the spring arms 9, said spring arms 9' beingattached to the bearings f of the type-carrier e, but when the pins 9en- .gage with certain guide bars upon the advance of the type-carriere, as will more fully appear, said pins are raised which act to cant thetype-blocks and bring them into conformity with the chimney. Beneath thetype blocks f as well as the central type block h are the springs fwhich act to cushion said type blocks f and h during the printingoperation. The central type block it remains stationary, being permanently secured at both ends to the cross-bars e Just in advance of thetype-carrier e and slightly to one side thereof is the rack i, said rackbeing adapted to slide to and fro in the guides z" formed in the frameof the apparatus. A cord or chain j is secured to the rear end of therack 73 as at 2' and passes thence over the pulley j secured to the stud3' of the frame. A weight k is attached to the end of the cord or chainj.

To provide for the advancement of the rack t' in its guides 2", a rodliscarried by the rod in the manner hereinafter described). A cord or chainZ is secured to the rear end of the rodZ to the lug Z and passes forwardover the pulley l secured to a depending bracket on the travelingcarriage. A weight Z is attached to the end of the cord or chain Z andas will more fully appear in the operation of the apparatus, the weightZ must be heavier than the weight is attached to the cord j.

The racki engages with the pinion m secured to the shaft m mounted inhearings in the arms m said arms being connected by the cross arms mThis chimney supporting frame formed by the arms m and cross-arms m ishinged at m to uprights m on the main frame A. This construction permitsof the swinging of the supporting frame toward the front end of themachine. The height of this supporting frame may be adjusted by means ofthe depending lugs m m on the rear cross-arm m The lugs m m are adaptedto be moved along the said cross-arm and the lugm is longer than thelugm In traveling along the cross-arm m the lugs m m come in contactwith the inclined top of the rib m whereby as said lugs travel up saidinclined rib m the supporting frame is raised to correspond to the sizeof the chimney to be printed on. Secured tothe inner end of the shaft 1%is the bracket 07. which supports the base of the chimney, said bracketn having the curved arms 11' pivoted thereto adapted to embrace the baseof the chimney and hold it firmlyin its grasp, and for this purpose thespring n is interposed between the lower ends of said arms at to throwsaid arms normally around the base of the chimney. To allow for theopening of said arms to remove a chimneyor insert one therein, pins 02engage with slots n on'said arm's n, the pins a being secured to thebracket n and traveling in the said slots 02, upon the opening of thearms it. On the shaft m is another pinion 0 which -meshes with a pinion0' on the shaft 19, said shaft extending over the frame of the apparatusto the opposite side and supported in suitable bearings. On the innerend of the shaft p is the pinion p which meshes with the gear wheel qsecured to the journal q. A bracket g similar to the bracket 12 on theopposite side is secured to the inner end of the journal q, and saidbracket is likewise furnished with curved arms 'r'adapted to embrace theneck of the chimney, after the manner of the curved arms n, beingprovided with the spring 4" and the slots or engaging with the pins r onthe bracket (1 The bracket g is further provided with a head piece 8 toprevent any longitudinal movement on the part of the chimney when heldby the arms of the brackets. This head piece 8 is secured at its ends tothe pins 8' on the bracket g the coiled springss being interposedbetween said head piece and the bracket to force said head piecenormally into contact with the head or top of the chimney, to aid in thesupport of said chimney. If de-" ICC Y type carrier 6.

sired thehead piece 8 canbe used in the base holder at as illustrated inFig. 8.

As hereinbefore set forth the type blocks f are so adjusted within thetype carrier as to be capable of being canted in their bearings f inorder to bring the face of said type blocks into conformity with thebulbous surface to be decorated. To. provide for this canting ofthetype-blocks f guide bars 25 are secured to the top of the framebeginning at points just to the rear of the chimney supports. The guidebars t have suiiicientfspace between them toallow for the passageof the-The rear ends of said guide bars 25 are provided with the inclined facest while the inner edges of said bars are beveled as at 25 so that on theentrance of the typecarrier e within the said guide bars, the pins 9 ofthe type blocks f will travel up the inclined faces 25 to gradually cantthe said type blocks, and then along the beveled edges t thuscantingsaid type blocks as long as the pins 9 travel along the bevelededges 1?. I

A bar or rod u is secured to the frame below the rack i, said rod havingthe stops or lugs 11. thereon with which the ends of the rack come incontact, when it moves back and,

forth thereby regulating the distance said. rack is to travel in itsguides.

In the operation of myimproved apparatus the several parts are firstbrought to their respective positions with relation to each other,

as shown in Fig. 1. The substance which imparts the ornamentation to thechimney is applied by a suitable roller to the faces of the type-blocksf andh and a chimneyis inserted in the brackets 71. and V g the base ofsaid chimney embraced by the arms n' and, the neck thereof by the arms0". Power is then exerted to drive the shaft cl, and through it thedriving chain 0. Since the driving chain c is connected to the carriagea by the crank incident with the advance of the carriage, a

and the type-carrier e, the rod Z has also been advancing, and just asthe type-blocks are about to pass under the chimney with their faces incontact and conforming therewith, the end of the rod Z collides withtherear end of the rack t. Upon the further advance of the carriage athe type-carrierewith its typeblocks f and h in contact with the chimneypasses under said chimney, while at the same time the chimney is rotatedin its brackets. For as the rod Z advances the rack 21 the pinion 'mrotates the shaftm' and the brackets n holding the base of thechimney,while through positions.

the pinions 0 o'the shaft 10 and pinion p and gear wheel q, a likerotarymovement is impartedv to the bracket qdsupporting the neck of thechimney. This simultaneous movement of the type-carrier e, with itstype-blocks in contact with the chimney, and the rotation of thechimney, will obviously produce the effect shown in Fig. 9, adesignconsisting of three clearly defined bands completely encircling thechimney. The rack t' is made of a length sufficient to impart throughthe mechanism described one complete revolution to the brackets 42andfwhich, supportthe chimney. When the type-carrier c has passed beyondthe chimney havingimparted the design to its entire circumference, asshown in Fig. 1, the rack 1' has reachedits extreme forward movement andabuts against the forward stop'u'i' on the I'Od/tQ WhilG the weight kwhich has beengradually elevated by the advanceof the rack t assumes theposition shownin- Fig. 4? The carriage a continues to advance a shortdistance after the stoppage ofthe rack '5 to permitof time to withdrawthe chimney before the carriage begins its retreat. It is evident thatwith the rod Z in contact with the end of the rack 75, the said rodcannot accompany thecar-riagein this further movement. The .weight Z?acts to hold the lug Z on the rod Z in. contact with the adjacent end ofthe sleeve Z, and said weight Z being heavier than the weightk, the.result is that as the rodZadvancesand meets the rack i saidrod drivesforward the rack iand raises the Weight 7a. 7 When the rackvl hasreached the extreme limit a of its forward movement, the rod Z is alsobrought to a standstill, but as the carriage still advances a shortdistance the sleeve Z willconsequently travel along the rod Z for ashort distance, the cord Z sec'u red to said rod passing up over thepulley Z moving with the carriage, thus elevating slightly the weight ZAt this stage of the operation the crank arm b passes over the frontsprocket wheel 0 when that portion of thedriving chain to which it issecured and which hitherto has been advancing, returns to the rear ofthe apparatus. Since said crank arm I) is also secured to the carriage athe said carriage together with the type-carrier e and rod Z return toresume their original Upon the first backward movement of the carriagect the weight Z will be lowered and. the arm Z resumeits former positionwith respect to thesleeve Z. After this sprocket wheel c' and againcarried forward the carriage a, when, a chimney having been inserted inthe brackets, the operation just described is repeated with the sameresult.

Any suitable substance may be employed for printing on the chimneys,either an ink or paste'containing the vitrifiable color, so that thesame is applied directly to the chimney, a sticky substance over whichthe powdered color or etching substance may be dusted, or an etchingsubstance in paste form. Such printing substances may either be appliedby means of inking rollers mounted on the machine and inked in theordinary way, or by means of a hand-inking wheel, the latter beingpreferable where the sticky substance is applied to the chimney, as oneapplication thereof will be sufficient for inking several chimneys, andthe operator can easily attend to the inking.
